If you missed some of the big headlines in tech this week — no stress! Re/code has you covered:
- On Wednesday, Microsoft held an event at its Redmond, Wash., headquarters and gave us a bunch of new stuff to gawk at. This includes a sneak peek at the Windows 10 operating system that will be out later this year, all the Xbox stuff Microsoft worked into Windows 10 and, of course, the new HoloLens holographic computing headset. We even took a test run of the device to Mars. It seems pretty neat!
- If you’ve ever accidentally deleted a bunch of photos from a smartphone or memory card, then you know that feeling of dread that courses through your whole body once you realize what you’ve done. Avoid the misery (and the R-rated tirade that’s sure to follow) with this handy guide to getting those precious memories back after you’ve deleted them.
- After pricing its shares at $14 apiece, Box’s IPO went just fine, thanks for asking. The company’s shares rose 65 percent after one day of trading, pleasing the market and Box’s leadership. Hey, maybe next they’ll turn a profit!
- Facebook said it’s going to get rid of fake news and other social media detritus that’s accumulating in your News Feed. Also, globally popular messaging service and Facebook mega-acquisition WhatsApp is coming to a desktop computer near you.
- Trivia Crack is the most-downloaded paid and free app in Apple’s U.S. App Store. Read about how that happened, and how this app is making big money for its makers.
- HBO will begin offering a Web-only TV subscription (probably in April) and in the process will probably gut the rest of its competition. How badly? Seven million subscribers could get rid of their cable TV, according to recent findings.
- T-Mobile CEO John Legere said the wireless carrier will now give its best-priced offers to all customers, regardless of their credit scores. Also, Google waded into the phone carrier business this week — and it doesn’t really seem like that great of an idea.
- How did the U.S. government know so quickly that it was North Korea behind the massive Sony hack that began in late November? NSA penetration of Chinese networks favored by North Korean hackers apparently did the trick.
- Ouch — 2014 was the worst year for job cuts in tech since the middle of the Great Recession back in 2009. A lot of this was due to “corporate restructuring” at big firms like HP or Microsoft, but still, not great news.
- SplashData’s annual worst passwords list is here, and a lot of people really need some help coming up with a remotely safe password. Two new 2014 entrants to the list: “696969” and “batman.”
